PHILADELPHIA -- The Philadelphia Phillies, the worst offensive team in the major leagues, received a boost from two unexpected sources Saturday night.

Left fielder Grady Sizemore had four hits and slumping second baseman Chase Utley went 2-for-3 with two RBIs as the Phillies beat the Arizona Diamondbacks 7-5.

Right fielder Jeff Francoeur homered for Philadelphia, which has scored 114 runs this season, fewest in the majors. The Phillies matched their season-high run total and extended their season-long winning streak to four.

"The last couple days we've been swinging the bats better," Sizemore said. "I think we've been putting pressure on the defense, getting guys on and just continuing to do that every inning."

Second baseman Chris Owings went 3-for-4 and first baseman Paul Goldschmidt hit his 10th homer of the season, a two-run shot, for Arizona.

Third baseman Yasmany Tomas also hit his first career homer for the Diamondbacks, who have lost three straight and four of five.

Sizemore had his first four-hit game since Aug. 21, 2008, while playing for Cleveland against Kansas City. He is hitting .405 in 12 games since May 1, raising his average from .147 to .275.

"Grady just seems to be clicking right now," Phillies manager Ryne Sandberg said. "He gave us some real good pinch hits to get him rolling. Now with some starts he seems to be in a groove."

Sizemore is also in a tough spot. The Phillies have a glut of outfielders and recently sent third baseman Cody Asche to Triple-A Lehigh Valley with the idea of making him an outfielder as well.

"You can't really worry about what you can't control," Sizemore said. "There's no need for motivation for any player. I think you want to go out there and get better every day. You just focus on what you can control and go from there."

Utley, a six-time All-Star and .285 career hitter before this season, entered the game batting .124. He batted sixth for the second straight day, the lowest he has hit in the order since 2005, and had just his second multi-hit day of the season.

"He's hitting balls away from the glove and the defense," Sandberg said. "That's good to see."

Sandberg also said that dropping Utley from third to sixth in the order would hopefully lead to "a little clearing of the mind as far as responsibility, and also a little relaxation."

Utley was not available for comment.

Philadelphia starter Jerome Williams (3-3) pitched five innings despite a 1-hour, 17-minute rain delay in the second, allowing three runs (two earned) and seven hits. He struck out four without walking a batter while improving to 3-1 in Citizens Bank Park this season. He is 0-2 with an 8.16 ERA on the road.

Jonathan Papelbon, the last of five Phillies pitchers, worked a perfect ninth for his ninth save.

Arizona starter Archie Bradley (2-1) lasted only two innings plus five batters in the third. He was charged with four runs and five hits while striking out one and walking three.

Bradley was making his first start since April 28 when he was struck in the face by a line drive off the bat of Colorado's Carlos Gonzalez, leaving him with a sinus fracture. Bradley was placed on the disabled list the following day and activated Saturday.

"He just had a tough night," Arizona manager Chip Hale said. "He struggled with his command and they hit him. ... It was not unexpected, coming back after what he went through. It's tough to get back in a groove after being out so long."

Bradley said getting hit by Gonzalez's liner is "kind of out of my mind right now." His greater concern was his faulty command.

"When you fall behind like that, you're going to get in trouble," he said. "I've got to throw more strikes."

Francoeur hit his third homer of the season in the second inning, a solo shot off Bradley.

The Phillies then added three runs in the third. First baseman Ryan Howard drove in the first with a double and Utley added an RBI single. The last run came home on a double-play ball off Francoeur's bat.

Diamondbacks shortstop Nick Ahmed had an RBI single in the fourth, and Goldschmidt's two-run homer in the fifth cut the Philadelphia lead to 4-3.

The Phillies answered with three runs on in their half of the fifth on RBI doubles by Utley, catcher Carlos Ruiz and pinch-hitter Andres Blanco.

A run-scoring single by Diamondbacks catcher Tuffy Gosewich in the sixth, coupled with Tomas' solo homer off Phillies reliever Ken Giles two innings later, shaved the Philadelphia lead to 7-5.

NOTES: The fifth-inning double by Philadelphia 2B Chase Utley was the 337th of his career, moving him into a tie for fifth place with Sherry Magee on the team's all-time list. ... Earlier Saturday, the Phillies acquired INF Jayson Nix from the Baltimore Orioles for cash considerations and assigned him to Lehigh Valley, their Triple-A affiliate. The 32-year-old Nix, a career .212 hitter in the major leagues, was hitting .167 for Triple-A Norfolk. He hit .154 in 18 games for the Phillies in 2014 before he was outrighted to Lehigh Valley. He refused the assignment and signed with Tampa Bay instead. ... To make room for RHP Archie Bradley, who was activated after being out since getting struck in the face with a line drive on April 28, the Diamondbacks optioned LHP Vidal Nuno to Triple-A Reno. ... Phillies OF Jeff Francoeur, who as a pinch hitter had the go-ahead RBI single in the seventh inning of Friday's 4-3 victory over Arizona, is 3-for-6 with three RBIs this year in that role. According to Elias Sports Bureau, he was just 4-for-30 with two RBIs as a pinch hitter in his career before this season.
